Week 8 - Challenge 3 - Coin Holder Design

AIM :

To create the Coin Holder Plastic component through the given Class-A surface.

OBJECTIVE :

• To make sure that the model meets the requirements of the draft angle.
• To create the Tooling axis using bisecting method.
• To perform Draft analysis on the given Class A Surface.
• To create the required Class B and Class C surfaces.
• To obtain a solid body from the surface using Close Surface feature.

CLASS A SURFACE :

• Class A surfaces are those surfaces which are curvature continuous while providing the simplest mathematical representation needed for the desired shape and does not have any undesirable waviness.
• The Class A surface is the used to begin the design of a product.
• All the further intricacies of the component are created based on the Class A surface.

TOOLING AXIS :-

PROCEDURE :

Creating Tooling Axis

• Initially a base surface was extracted from the Class A to create a center point.
• An axis system was created upon this point.
• The Intersect feature was used to obtain a boundary of the Class A intersecting at the mid plane.
• Once the check for the discrepencies in the boundary is done, the Tooling axis was created from thr mid-point.

CLASS B SURFACE :-

1. SIDE WALLS:

• To create a side wall by extract the class A side faces
• To untrim the extracted side walls
• To extrapolate them for make sure to pass through all together for merge
• To trim the unwanted faces from walls by trim
• To offset the walls up to 2.5 mm

3. BASE:

• To create a base by extract the base from class A
• To untrim and extrapolate the base for final trim to create a B-surface

TOP WALLS:

• To create a top wall by Mutiple extract the class A side faces
• To extrapolate them for up to requirement
• To offset the walls up to 2.5 mm

CLASS C SURFACE :-

• To use multiple extract tool on the class A surface
• The extract boundaries can be sweep at 90 degrees to the reference boundaries up to required length

FINAL SURFACE :-

• ISOMATRIC VIEW :-

• TOP VIEW :-

• FRONT VIEW :-

• VIEW :-

DRAFTING :-

1. THE DRAFTING VALUE, I GET IS IT 2.90 TO 2.98.
2. IN DIFFERENT POINT ON THE SURFACE OF COIN HOLDER.
